Power Management

Date project November 2017
Customer Camerge

Demand
Via connection TTL and using protocol NBR 14522 receive data from power meter and send to webservice in the JSON file format.

This project consists of receive data from power meter that are sent every second and save in local database to after the 15 minutes send it to the webservice.

The power meter can be setting to two operation mode: normal or extended, the software detect how user interface was configured to data process, all communication is made in C and saved in local database, after then using Linux’s script the data are sent.

G-Force Meter

Date project, April 2017
Customer Jumil

Demand
G-Force meter for resistence testing on machine, save data in card microSD in the format CSV.

This project used an accelerometer as sensor to g-force meter, in most cases the acceleration is used as a vector quantity, which can be used to sense the orientation of the device, more precisely pitch and roll. Because when you turn the device, the 1G component is distributed among those 3 axes. With simple vector math we can calculate the angle of the device.
